Application ma m 2a, 1903. Serial Nowassa Tow/ll whom itmay'eoneei'n:

Befit known that I, GEORGE H. GRESHAM, a citizen of the United States of America, and a resident of the borough of Manhattambity, county, and Stateof' New York, have invented certain new'and useful-- Improvements in Temporary Binders, of which "the following is a specification. p

1 My invention-relates generally to term 0- rary binders or loose-leaf books, and,'wl 1i.le not limited in its a plication to a particular typeor size 0i boo the invention as herein embodied is specially designed for use in con-.

necti-on with the .class' known as .niemo-' randum or price? books and the like.

My invention injits xpreferred form is illustrated in the V accompanying drawings, throughout the several views of which li e numerals of reference parts. V j i In he drawings, Figure 1 is a view in" erspective of a. loose-leaf book bonstruete in accordance with-myinvention, .the saine being sho' wn. open or with the :eover thrown;-

back. Fig: 2 is asimilar view showing the. binder adjusted for theinsertion or removal of one vormore sheets; Fig. 3. is a view in ook and portions of the casing broken; away to moreclarly show the construction and ,an angement of. the operating p'arts. Fig.4 is abottom plan'fview of the same, sho I the relative position of the slide-bar when t e leaf-retaining j'aws are-closed.

Fig. 5 is a similar view showing the slide-bar in an adjusted positionjto o en the leaf-retaining jaws. Fi 6 is a etail. cross-sectional view thereo i, taken on the line s 3" of Fig. 4. Fig. 7 is a view: inperspective of a modified form of binder with portions of the casing broken away to show the iope'rating parts. Fig. 8 is a cross-sectional view taken on the line 8 s of Fig. 11, showingfthe leafretaining jaws open. 91is a similar view showing the jaws closed, Fig. 10 is a bottom plan view, and 11 is a longitudinal Fig. 10.

but it, will be understood that I donot wish to in any wise limit myself to the use of the same, as it forms no'part of the present invention and is merely employed hereinlfor the urpose of completing an operative illustration. "Other types, styles, s1z'es,&c.,may

I

The plate 6 is stamped up from sheet metal and sultably shaped to contain the o erating parts of the binder. It is flanged ongi.

" tudmally'by having its opposite edges "8 8- bent over and as a convenient meansofse the same to the cover a number of in tegra spur-like projections 9 9 are provided as extensions 'of the flanges, and after being forced through the cover of the book they are secured by having their projecting extremities'bent over in opposite directions.

The sheet-locking jaws project in pairs through slots oropenings in the plate and when used iii-connection with memorandum or other small size books are formed of flat or round wire. In the preferred form the jaws 5 5 and 5 5 of each pair are formed by the bent-up extremities of wires or rods 1-0 10,

which extend side by side along the under side of the plate and are held in position by The ening and closing of the jaws arepreferab y effected ositively by means: of a peculiarly-slotted s ide-bar-12, and, as will on thejunder side be seen-,"the operationor adjustment of the' jaws does not, "therefore, dependiupor'r the resilientfql l'alities offthe metal forming the wires 10 10, It willbo understood, however, that while,the*use of highly resilientmetalis not essential} i V y it may bei 'made to" serve in' fassistin'g'fthe vac-J tio'n '.of ;,thei; slide b rggeith on: opening or; closing-the jaws.

, As the foperation' will -l' e generally understood fr'oiIn the foregoingdescription, I shall describe the same briefly.

When it desired to remove or insert'one or n1ore"l ea'ves, the book is opened at th epoint s usegis not objectionable, "as

where such insertion or removal is to be made and the slide-bar is drawn outward by grasping the rojecting thumb-piece. This movement of the slide causes the wedge-points to cam 15 5 the wires apart and separate thejaws, as indicated in Fig. 2. After the insertion or removal of sheets has been effected the jaws are forced together or closed by 'pushingin the slide, and the book is ready for use.

Some of the main advantages of my invention are asfollows: The device in its preferred form employs only three or four parts of inexpensive construction, and being extremely simple, light, and strong it is particularly wel adapted for books of the class describe as it answers all requirements, increases their eostvery'sli'ghtly, and 'ermits such books to bef'profitab'ly markete at a comparatively low cost'of manufacture. 7o
